well my buddy had some old fog lights he doesnt want anymore so he gave them to me and this weekend i want to install them in my bed for bed lights, ive been searching all day on how to wire them up and still am a little lost on it. I had a little experience with wiring up subs and stereos but never ran anything to a switch before.

i have no idea how to work a relay or wire one up, i found one person that put an add-a-fuse to his original fuse box under the hood and then just ran a wire from that to his switch and then to the lights. am i correct on this?
